Title:
二酸化炭素吸収材、二酸化炭素吸収材の製造方法、二酸化炭素分離体および二酸化炭素分離回収装置
Document Type and Number:
Japanese Patent JP7333674
Kind Code:
B2
Abstract:
The invention provides a carbon dioxide absorbing material in solid form, capable of separating and absorbing carbon dioxide from a gas containing carbon dioxide, and recovering the carbon dioxide efficiently and in an energy-saving manner, at a vacuum pressure that is only near ordinary pressure. The invention also provides a carbon dioxide absorbing material production method, a carbon dioxide separation body using the carbon dioxide absorbing material, and a carbon dioxide separation recovery device. This carbon dioxide absorbing material is characterized by comprising an organopolysiloxane containing secondary amines, which is represented by general formula [I] and has a three-dimensional structure. [Chem 1] [I] (SiO2·SiO·6CH2)n(NH)x(2CH2)x-1 (in the formula, n = an integer of 10 or greater, and X = integer of 1 to 10.)
